Here are three more things I've recently learned that you cannot do on a plane:

Paint your nails. Passengers may not apply nail polish mid-flight either in their seat or in the lavatory. This is true even if they "only have two nails left to paint." CONSEQUENCE: Passenger will be handcuffed by two police officers when plane lands and taken to local police station.

Warn passengers, incorrectly, over the PA system that the plane is going to crash. Flight attendants may not order the pilot to return to the plane to the gate due to perceived technical difficulties and, if the pilot refuses this order, may not say "Captain, I am not responsible for crashing this plane" over the PA system. CONSEQUENCE: Flight attendant will be forcibly removed "kicking and screaming" from aircraft by passengers and other flight crew.

Bring a rabbit onboard a flight. Passengers may not bring an "emotional support animal" that is a rabbit onboard a flight even if the support animal has all proper documentation and is listed on reservation. This is due to the fact that some flight attendants incorrectly believe rabbits are rodents, and rodents are prohibited onboard. CONSEQUENCE: Passenger will be forbidden to board with rabbit and must make separate reservations on another airline for three times the cost.
